Triangulated Control Technology
All Gammaflux hot runner temperature controllers feature
Triangulated Control Technology . Using this unique technology,
our controllers:
1) Sense – 20 times per second, Gammaflux controllers precisely
measure the thermocouple;
2) Control – the proprietary self-optimizing Gammaflux PID 2 control
algorithm adjusts if the actual temperature deviates 0.1º F (0.05º C)
from setpoint. The second derivative (PID 2 ) monitors the actual
temperature rate of change. As a result, the LEC module regulates the
output to the heater in advance of achieving setpoint to limit or
eliminate over or undershoot.
Gammaflux is proud to introduce the new LEC
temperature controller. The LEC provides a true
breakthrough in hot runner controller performance and
affordability. No longer do you have to pay top dollar
to get top hot runner temperature control. Best of all,
the LEC offers field-proven Gammaflux performance
and reliability.
Control for Up To 24 Zones
Designed for smaller hot runner system applications,
the LEC is offered with 2, 6 and 12 zone enclosures.
A network module allows you to link two 6 or 12 zone
enclosures together for up to 24 zones of control.
The LEC features a modular design for simple control
card removal, addition or replacement.
Extensive Diagnostics
Each 6 and 12 zone LEC enclosure comes prewired,
ready to accept an optional network module. With a
network module, users can connect the LEC to a laptop
or PC to take advantage of advanced features including;
security settings, remote input, and unique Gammaflux
software including Gammavision (SPC data/graphing
analysis), Mold Doctor (advanced mold troubleshooting),
and Field Calibrator. The network module also enables a
link to plant monitoring systems.
3) Actuate – using phase angle fired output, the Gammaflux controller
delivers smooth and exact power to each heater in 0.24 VAC increments
for the ultimate in temperature control.
Triangulating your process with
a Gammaflux controller means
achieving better temperature control,
that could result in:
• enhanced part quality
• reduced scrap
• improved part weight
consistency
• material savings
• higher profit margins
Power Priority
“Low mass”, or extremely small
hot runner nozzles are a unique
challenge to control. To smooth the power and
ultimately the melt heat history, Gammaflux has created
Power Priority . Power Priority smoothes the power output to
individual zones. Users have the option to manually apply a
Power Priority set point from 1 (light) to 4 (heavy) output,
providing unparalleled control for applications where it is most needed.
Protection
Closed loop wet heater bakeout - 120 times per second (at 60 Hz), the LEC
module checks the heater for a short, steadily ramping up the voltage for the
fastest possible time to set point. If the heater is wet or shorted, the output is
adjusted within 8.3 milliseconds to protect the heater, cables and controller.
